Ever wondered how much do you actually know about the 3 phases of matter? Check out the interesting quiz questions from our online 3 phases of matter quizzes, choose the correct answer from the given choices, and prove your knowledge.

• 1.

It is rigid, has fixed shape and fixed volume. What state of matter is it?

• A.

Solid

• B.

Liquid

• C.

Gas

A. Solid
Explanation
A solid is a state of matter that is rigid, meaning it maintains its shape and volume. Unlike liquids and gases, solids do not flow or take the shape of their container. Therefore, the given description of a substance having a fixed shape and volume aligns with the characteristics of a solid.

It is not rigid, no fixed shape but also no fixed volume. What state of matter is this?

• A.

Solid

• B.

Liquid

• C.

Gas

C. Gas
Explanation
Gas is the correct answer because it is a state of matter that does not have a fixed shape or volume. Unlike solids and liquids, gases are able to freely move and expand to fill the space available to them. Gas particles are in constant motion and have a high amount of energy, which allows them to move independently of each other. This lack of fixed shape and volume is characteristic of gases.

It is not rigid, no fixed shape but has a fixed volume. What state of matter is it?

• A.

Solid

• B.

Liquid

• C.

Gas

B. Liquid
Explanation
A liquid is a state of matter that does not have a rigid or fixed shape, meaning it can take the shape of its container. However, it does have a fixed volume, meaning it maintains a constant amount of space. This characteristic distinguishes it from gases, which do not have a fixed volume, and solids, which have both a fixed shape and volume.

What state of matter can adopt a highly ordered packing arrangement and that structure is said to be crystalline?

• A.

Solid

• B.

Liquid

• C.

Gas

A. Solid
Explanation
Solids are able to adopt a highly ordered packing arrangement and have a crystalline structure. In a solid, the particles are closely packed together in a regular pattern, forming a three-dimensional lattice. This arrangement allows the solid to have a fixed shape and volume. In contrast, liquids and gases do not have a highly ordered packing arrangement and their particles are more randomly distributed, resulting in a lack of a definite shape and volume. Therefore, the correct answer is solid.

• 5.

Which state of matter has a collection of widely separated molecules?

• A.

Solid

• B.

Liquid

• C.

Gas

C. Gas
Explanation
Gas is the state of matter that has a collection of widely separated molecules. In a gas, the molecules are not tightly packed together like in a solid or liquid. Instead, they are spread out and have a lot of space between them. This allows the gas to easily fill the container it is in and to flow and expand to fill any available space. The molecules in a gas also have a lot of kinetic energy, causing them to move rapidly and randomly.

What is the name of the process when a liquid changes into a gas ?

• A.

Vaporization

• B.

Sublimation

• C.

Melting

• D.

Condensation

A. Vaporization
Explanation
Vaporization is the correct answer because it refers to the process when a liquid changes into a gas. This process occurs when the temperature of the liquid reaches its boiling point, causing the molecules to gain enough energy to break free from their liquid state and become a gas. Vaporization is commonly observed when water boils and turns into steam.

What is the name of the process when a solid directly changes into a gas?

• A.

Vaporization

• B.

Condensation

• C.

Sublimation

• D.

Melting

C. Sublimation
Explanation
Sublimation is the process in which a solid directly changes into a gas without going through the liquid phase. This occurs when the temperature and pressure conditions are such that the solid particles have enough energy to overcome the intermolecular forces and transition directly into the gas phase. Examples of substances that undergo sublimation include dry ice (solid carbon dioxide) and mothballs (solid naphthalene).

• 8.

What is the name of the process when a solid turns into a liquid?

• A.

Sublimation

• B.

Vaporization

• C.

Condensation

• D.

Melting

D. Melting
Explanation
Melting is the correct answer because it refers to the process in which a solid substance changes into a liquid state. During melting, the particles in the solid gain enough energy to overcome their attractive forces and start moving more freely, resulting in a change of state from solid to liquid. This process typically occurs when heat is applied to the solid substance.

Rate this question:

• 9.

In which state of matter do the particles have the most energy?

• A.

Solid

• B.

Liquid

• C.

Gas

C. Gas
Explanation
Gas particles have the most energy compared to particles in solid or liquid states. In a gas, the particles have high kinetic energy and move freely in all directions. They have enough energy to overcome the attractive forces between them, allowing them to move independently and rapidly. In contrast, particles in solids have the least energy as they are tightly packed and vibrate in fixed positions, while particles in liquids have more energy than solids but less than gases as they can move and flow but still have some intermolecular attractions.

Rate this question:

• 10.

Which amongst the three states of matter have the least density?

• A.

Solid

• B.

Liquid

• C.

Gas

A. Solid
Explanation
Solids have the least density among the three states of matter. This is because the particles in a solid are tightly packed together, resulting in a smaller volume compared to liquids and gases. The particles in liquids are more loosely packed, while gases have the most space between particles, leading to higher densities in comparison to solids.
